licensing: add spdx to our .cocci files Since those are chunks of code based on our codebase, it's easiest to use the same license. 2021-10-01 10:28:36 +00:00			`/* SPDX-License-Identifier: LGPL-2.1-or-later */`
coccinelle: always use fcntl(fd, FD_DUPFD, 3) instead of dup(fd) Let's avoid fds 0…2 for safety reasons. 2018-03-20 19:57:37 +00:00			`@@`
coccinelle: further restrict certain transformations Some transformations generate results we don't want to keep, so let's disable such transformations for specific files. Also, disable const-strlen.cocci everywhere, as the STRLEN macro has a pretty limited scope, so the transformation generates false positives in most cases. 2019-04-29 14:12:41 +00:00			`/* We want to stick with dup() in test-fd-util.c */`
